Investigating and analyzing the structure of the row and rhyme of Hafez's poetry From the perspective of relative frequency construction and syllable pattern

Extracting components to determine the author's personal style is one of the things that can show the author's style more accurately and better based on measurable parameters. One of these parameters is the study of the relative frequency of a particular structure. In this regard, the study of the syllabic structure of the row and rhyme can be effective. For this purpose, this research has tried to determine the frequency of construction and the syllabic pattern of rows and rhymes in Hafez's poems. The study also aims to examine the extent to which Hafez uses each of the syllable structures in the row and rhyme and the arrangement of these structures in each syllable pattern. This research shows that the ratio of syllable construction in Hafez's poetry is somewhat in harmony with the natural Persian language. In terms of syllable pattern, the poet has used a wide variety of patterns. In terms of frequency, the patterns used also have different frequencies. Although the poet has shown no interest in using open syllables in the one-syllable pattern, he has used this syllable well in multi-syllable patterns.This study shows that the poet has limitations in using some patterns, such as not using patterns that start with cvcc in two-syllable patterns. This study also shows that in the application of each of the constructions in total patterns, the construction of cv is superior to the constructions of cvc and cvcc. In terms of the average use of each of the three constructions in all row and rhyme syllables, cv syllables are in the first place and cvc and cvcc syllables are in the next positions, which in terms of both rank and relative frequency is accompanied by spoken and written language.
